Steel guard your home steel doors in connection with the crime situation ceased to be a symbol of just rich flats and protected institutions. Now, virtually everyone, regardless of the abundance of lessons in the home of "good", wants to ensure his safety, and, hence, peace of mind. About what we choose the steel doors and how to install and will be discussed below. Steel doors are divided into two groups: domestic and imported. They differ primarily at the cost of (imported, of course, more expensive). But savings are not in all things good. The fact is that from abroad bring doors made with modern equipment and latest technology. But our doors are all going to artisanal, "on his knee." However, there is another side to the problem. Most often imported models are "tied" to the typical size (with each company - its). But the domestic steel door can be custom-made (and, by the way, just because it is non-automated production). Well, if people can pick out the appropriate size of the door of the proposed import models. And if not? Then the door can cost a lot more expensive, and it certainly will have to wait up to two months, and sometimes up to six months if the order is exclusive. If you have time and money to spare, you can wait. Otherwise - select domestic. Surely, if you choose the door you are thinking about it, not only as a reliable protection (it certainly), but also as an integral part of the interior. By installing one steel door, do not even want to admit the thought of her shift, but the interior of the house can be changed more than once. Modern steel door must not only allow you to change its appearance, but also can set the tone in the choice of style. Therefore, we recommend the construction of doors, which makes it easy to make such changes. Another piece of practical advice that will be of particular interest to newcomers. Front door - this is usually the first of a long chain of repair that needs to be done, and dignify her expensive finishes on this first stage, sometimes risky, given that it will pass through the masses of workers and building materials. Rational solution: You can remove the existing panels and put them back after repair, or when ordering door zakomplektovat its inexpensive finishes, and when the time comes to interior design to select an appropriate style and color. Device on the device all the steel doors are similar. At the core - a rectangular frame with internal stiffeners, welded from steel profiles. On the frame is welded steel sheets (with one or both sides). Any steel door hung on hinges in the steel frame that reinforces the doorway. Outside the door leatherette stud or decorative panel (the most expensive finish - natural wood). Often offer a door painted with powder. Inside the door can be hollow and may contain proofing and insulation material. Several options: Basalt Mineral wool or polyurethane foam plate. And sometimes the sound quality and noise isolation of the pressure zapenivaetsya polyurethane foam. Glass for doors in a residential area is not used. The difference of import and our door "Anatomy" can consist only in the thickness of steel sheets. Abroad put sheets no thicker than 1.5 mm, we use a steel plate with thickness of 2-3 mm. As a result, our doors are obtained by a massive and heavy. But some experts argue that it does not always mean that they are reliable. Rather, the more weight once again "feels" hinges for durability. What else should consider? The presence of casings and chapels. Clypeus - part of the door frame, covers the gap between it and the opening, in which the frame is inserted. Why frames? First of all, without them the door looks worse, and secondly, the scrap is easier to operate: the attacker enough to squeeze through a crack in the scrap and turn out a design surface. Trims significantly complicate the embodiment of evil designs. Porch also makes the steel door more secure. Narthex - a serving piece outside the door leaf or the inside of the frame, closing the gap between them when the door is closed. Vestibule makes it difficult to use crowbar. And with good doors and a porch on the door frame and the door leaf. Keep in mind: to import the steel doors of the porch and the trim is optional, but domestic doors can not have them. True, and the price is lowered by about 10%. But this is the case when the miser pays twice. Almost all modern steel doors look very aesthetically pleasing hard choices now as relevant as ever old English saying "My house - my fortress." Is this you? After all, real security can only provide reliable high-quality steel door with secure locks and special devices. The steel door will not only give you confidence and a sense of security, but also complement your home comfort and aesthetics. Steel Door - protection not only from intruders but also from the noise, drafts and other adverse impacts from outside. Are all steel doors and their manufacturers are equally reliable and convenient? Of course not. Options and offers a great variety! Quality doors depends not only on the quality of the material, but also from the manufacturer, not chasing short-term profits, but try to establish itself as a reliable company. Want to buy a good, comfortable, reliable door - do not ask for the first caught the eye of property, and try to choose a reliable, has already proved itself in the market the company. But among them try to pick the best, one that can offer you the greatest variety of finishing steel doors, according to your needs and capabilities. When choosing a steel door, the customer expects that his being robbed - this is the main concern. And yet - that the door properly and will last a long time, and if something happens (eg, loss of keys, breaking locks), everything will be quickly corrected. Believe our experience that Repair care is inevitable you will have, at least from a desire to change the keys. Question: How fast? After a month, year or in five years. Unlike steel from the tree, here manifested in the fact that almost any repair of a steel door is a complicated and expensive operation. Replacement and repair of the most common now, the so-called Safe (spacers) locks often entails disassembling a steel door, in particular - complete dismantling of the decor and fittings. Therefore ordered the door to a firm with a good repair facilities. About Locks & Accessories According to experts, the most reliable locks - lever, they are also most often - crab (when the "tongues"-bolts go into 2-4 directions on different sides of door leaf). The more complex lock, so it is more expensive. Experts advise on a door to put at least two locks. One - crab, the other - simpler. It is desirable that one was a lever lock, the other - cylinder. The larva of the cylinder lock should be protected armored plating so that it was impossible to dislodge. Well, when deadbolts locks hidden in a metal tube that can rotate - then bolts can not saw through. Another important element of good steel doors - hinges. Again, they may be foreign, and domestic production. By the way, came onto the market new items. For example, all the steel doors let into protivosemnye pins. This is the "spikes" will help to keep the door to the door frame when the robber hit by a hammer loop. The number of pins varies from 2 to 4. In addition, choosing the door, you need to pay attention to how powerful the loop, ask the seller how much weight they are free to stand up (the most reliable hinges are hinges on the support bearing). Number of loops is calculated individually for a particular door. Statistics say that your steel door will not crack, unless you make a mistake in choosing the locks. It is important that "painful" points of the castle was protected by armor inserts. In cylinder locks have two advantages. First - small size keys, and they come with beards, or with holes (more expensive). The second of their dignity, especially important for steel doors - easy replacement of keys. It's enough to replace the cylinder mechanism, in common parlance often referred to as larvae. Alas, to replace the keys in the lock lever will certainly need to be removed from the lock all the doors, and it as already noted, means the complete dismantling of decor and fittings. This is true for lever locks domestic production, as well as the most famous castles in our foreign firms - Cisa, Mottura, Mul-t-Lock. Pleasant exception are locks of Italian firm «ATRA», specifically designed for steel doors and safes. The theme of castles adjacent electronic locking systems and security. The cheapest, and therefore, the most common ones are electronic locks blockers, which are controlled by pressing a button on the fob, just like in the car. This lock makes it impossible, in principle, opening locks with master keys. Very useful, though not cheap audio, video features to restrict access. Any respectable company will offer you several options for such systems. Generally, the locks - this is the most important thing is that you have to choose. Locks must necessarily be two - the main and backup. At least in order to lock the door on one, while the second repair. And finally, accessories Firstly, the peephole. Good eyes - with a radius of view of 200 ° C. Imported doors without buds do not. Our eye is usually put on order. By the way, if you want you can order a peephole installed at a distance from the floor, so it could look a child. Another neat detail - the inner gate. And better to get a screw bolt, and not moving: it collapses under the door may accidentally close. You can even put a chain or a mechanism with the same effect. But this - is optional. Now, steel doors put even in the churches Installing a steel door So, let's door you have chosen. Now you can call a vending company and invite you to zamerschika, or better yet - an engineering consultant. He will recommend the most appropriate model (taking into account the peculiarities of the name of your apartment). For example, let you know that the door to the cottage should be chosen with such a surface that she was not afraid of humidity and temperature fluctuations. In addition, you will help determine what features of the access opening walls, etc. Then, together with zamerschik need to make cost estimates. And do not forget to sign the agreement to install the door. It is very important to carefully study the text of the agreement, make sure that all the items you like. It is possible that at the moment of signing the contract will need to pay a deposit (but not more than 50% of the total). And to get the deposit is only entitled to "a person with power of attorney the right to receive the money." Now we must wait until the door is made (or will deliver if the door is imported). Typically, it takes several days to two to six months, depending on the complexity of the order. After that will come to your house team of installers, who, naturally, and install door. By the way, installing a steel door does not particularly different from the plant, for example, wood. First, the wizard "expose" the door frame a special device called a "level" (ie set it so that it hung strictly at 90 ° C). Then attach the door to the doorway long rods or anchor bolts. Warning: It is important that the pins were as far from the outer surface. This will prevent the door securely against hacking. In principle, the steel door can be installed and overlap (ie, outside the doorway). But this is an inefficient and inelegant option. Therefore, most doors are flush with the edge of the doorway. In this case, the door unit deepen in the door. From a security standpoint is the best option - installing interior door opening. But in this case there is one drawback - the door can be opened to a maximum of 90 ° C. Alas, there were cases when the installers from unscrupulous firms asked the owner to bring a glass of water, close the window, etc. Be careful: perhaps, mountain-masters want to use the exhaust method and pour the sand into the loops, so as not to align the door properly. Properly installed door should not "walk" (ie it remains in the position in which it left, but not locked and can not be opened at random). But it happens that the client can make requests so that the door closes by itself. Accepted the job and pay off the contract, be sure to get a copy of the completed form, which states that you have paid in full. All documents must bear the stamp and signature of the responsible parties. Also, do not forget to take your warranty card for free repair of the door. (It will be so helpful, if a fault occurs suddenly due to the fault of the manufacturer or installer.) And to specify what the warranty period set to your door. By the way, if the warranty on the steel door is less than a year, generally do not recommend buying it. Solid firms provide good five-year work of his models, foreign - from 5 to 10 years (and some up to 20 years). It is important to guarantee the same spread at the door, and its separate parts (locks, finish). The British once calculated that the cost of all protective and security measures, including doors, grills, alarms, concierge work, etc., should not exceed 1 / 10 -1 / 6 the cost of a protected property. So it is quite possible that the need for peace of mind is not the most expensive door. While a good defense in our troubled world will never be superfluous. An important element is a steel door hinges. Since the vast majority of the steel door opens outward, the outside are welded and loops. Typically, this is a little rough aesthetic element of the door, and often - causing the customer concern. "And suddenly srezhut?". But what's really worth to pay attention, because this is - that the loop contained a thrust bearing, either - the reference hardened ball. It is a guarantee against abrasion loops, one of the causes extremely unpleasant phenomenon - sagging door. Concealed hinges few words on the hidden hinges. The advantage of this enhancement of steel doors is that they are inside the boxes and their absence from the outside improves the appearance of the door. Although, over the millennia people have used to seeing the doors to the hinges and their presence is unlikely to cause confusion. Another thing, if the outer loop are massive, they can spoil the overall picture. It is also believed that the hidden loops affect the protective properties of the door (the door can not open by cutting the loop). From this view you can argue. First of all: virtually all manufacturers of steel doors that have open loops provide the design elements do not allows to open the door even with truncated loops. Second: The cutting loops - loud enough and long operation, requiring the use of cutting equipment and attract attention. Not everyone on it will be decided in a residential house, and knowing this about the existence of the doors protivosemnyh elements. At the same door with concealed hinges have several disadvantages. First: These doors do not open more than 95 degrees, which reduces the size of the clean aperture. Secondly, if the fully open the door leaf to make an effort (as if trying to open it more than the 95 ° C), we can deform the inside of the box in the place where the welded hinge. Can also deform the bracket connecting the door leaf with a noose. In both cases, the door will be closed or skewed, or cease to be closed altogether. The same thing can happen if a heavy enough fabric in the opening does not hold, and leave in the free inertial motion. Door open loops in this case will be free to move to strike the wall. In this case, can only damage the door handle and wall coating. There are designs of doors, where the hidden loops are set according to the type of safe, ie not in the side rack box in the upper crossbar and into the doorway. In these doors do not have the bracket connecting the door leaf with a noose. Therefore, in the above cases, the strain can be subjected to and the box and the canvas. Often the design of the door with internal hinges is such that it is impossible to remove the canvas from the box. This resort in the event of Bringing a marker of things. Or, for example, in case of repair cloth, then, without time-consuming and expensive process of dismantling a door block this repair may not be possible.

Or, for example, in case of repair cloth, then, without time-consuming and expensive process of dismantling a door block this repair may not be possible. Look, just focus on the quality of fit seal by hidden loops (or even his presence in this area) because it happens that technologically impossible in such designs to establish (or well established) seal. And then, for good heat - insulation need a second door. Caring for a steel guard for a long-term operation (steel doors), metal door, it is necessary for the ability to perform a number of recommendations set out below: It should not be inserted into the keyhole of foreign objects, to avoid breaking the lock. Do not close the door when nominated girders locks to prevent them from skewing recommend regular oiling locks, sip screws. Suggest that once a year to call a specialist firm on the manufacturer for maintenance. In operation (steel doors) of a metal door to keep in mind that decorative trim more exposed to external factors, such as: humidity, temperature, mechanical impact. it is desirable to finish the street door was protected from the action of moisture and direct sun visor. Also, be aware that the finish of solid wood or veneered wood, covered with furniture polishes, and care for such a finish is carried out according to the requirement to care for furniture and wooden products. Do not wipe decorative finish any solvents (benzene, acetone, kerosene, etc.) should know that the operation of a metal door on the premises with the presence of plaster, cement and other construction dust, requires the protection door locks and decorative finishes. When the shelter with watertight films wooden panels in wet areas, on the last condensation, it is recommended to repair time is not set decorative panels and install them immediately after the repair. Metal door fairly complex device, so we recommend regular maintenance. Also, our specialists can make restoration of the decorative panel, after several years of operation. On the question of fire doors. In a system of measures to ensure fire safety of buildings and structures for various purposes occupies an important place to use fire barriers. The main purpose of these structures - to prevent the spread of fire, create conditions for the safe evacuation of people, access the fire brigade to the hearth fire, and actions to save lives and property. Constructions of this type, based on their functional characteristics, can be divided into general and local. The common fire barriers are walls, partitions, floors. The local - the doors, gates, manholes, valves and etc. But if on the design, materials, construction technology first say and write a lot, then about the second group is clearly not enough. This creates significant challenges for those who design and forms an individual image of the buildings, and for those who exploit them, reconstructing or simply completes. Let us dwell on the products of the latter group. Analysis of the requirements of the recent consumer to fire doors, points to their qualitative change, resulting in our opinion the following factors. Today, fire doors are increasingly becoming full participants in a comprehensive solution interior, and in some cases, the appearance of the buildings, and the consumer is not satisfied with designs made in the form of a wooden frame filled with asbestos board or mineral wool and sheathed with galvanized sheets. Color, coating quality, design concept, decoration, used accessories is now worried about the consumer not less than the operational characteristics of the door. Moreover, these parameters of the product, largely related to (until recently) to the wooden structures are transferred to the consumer and is traditionally used in practice, steel fire doors. Taking into account a wide range of modern materials and technology, these properties are not difficult to be implemented, if it did not apply to fire doors, the main parameter which is resistant to fire, which is characterized in the regulatory and technical documents as the limit of fire - EI. This parameter specifies the time within which the door design saves characteristics such as integrity (nevypadenie leaf out of the enclosing structure) and the insulating ability (ie, the design ability to withstand a temperature increase on the unheated surface.) The above parameters are achieved by the application of specific design solutions and leaf boxes, and use as filler insulating material that is significantly different fire doors of conventional construction steel doors. For example, the number of domestic firms is used for making boxes steel tube of rectangular or square formed by the connection porch and clypeus. However, this traditional, conventional steel doors way to a constructive solution to the box, usually limits the fire door assemblies 30 or 45 minutes. The most promising in terms of both performance and appearance is the use of steel profiles. In this case, taking into account the technological capabilities of the manufacturer's box is a complex profile, made of sheet steel, or assembled from several special sections. In both cases, the box is a rigid structure and at the same time forms a casing. It withstands the tests over 60 minutes. Cloths fire doors are made in the form of boxes, whose thickness is determined by the applicable insulation materials, as well as the constructive solution of the heat package as a whole. As insulating materials are widely used slabs of mineral wool on the basis of basaltic rocks of different density and the sheets of drywall. The formation of insulating "endvicha" defines design and heat insulation capacity is to "know-how of each manufacturer.
